yes, i have been using etherdelta for quite a while now and so far i havent encountered any problem. But just to be sure, after trading, you should cash out immediately. And make sure you only deposit coins that you wanted to trade, not the entire balance of your wallet.
Thank you for your information about the EtherDelta, I know it is safe if the website is not fake, but I do not like to trading there since it is not so friendly to users.
